The wide variation in skin tone in humans is due to a combination of genetic factors and environmental adaptations. Skin tone is determined by the amount of melanin in the skin, which varies based on genetics and the need for protection against UV radiation in different climates. Over time, populations have evolved to have different skin tones based on the level of sun exposure in their environment.
